Abstract

A railway axle is described of the type in which a rolling element bearing is mounted within a seat defined between two members, a first of which rotates with respect to the second, and is provided, externally of the seat, with a sealing assembly adapted to protect respective rolling bodies of the bearing; an annular element of the sealing assembly is fixed for rotation with the rotating member of the axle and is provided with a plurality of permanently magnetized zones having substantially the same width circumferentially spaced from one another with substantially constant pitch; within the seat and close to the said annular element of the sealing assembly there is further provided a sensor carried by the fixed member of the axle and adapted to be activated by the transit past it of the said magnetized zones to generate a periodic signal having a frequency proportional to the number of these which transit past the sensor in unit time.
